Double-curved-surface UHPC curtain wall unit plate construction method based on BIM technology

Abstract

The invention discloses a double-curved-surface UHPC curtain wall unit plate construction method based on the BIM technology. The method is characterized in that the method comprises the steps that S1, an information model of a double-curved-surface UHPC curtain wall is built; S2, the information model is divided into a plurality of unit plate models, and installation parameters of each unit platemodel are extracted; S3, a 3D template of each unit plate model is engraved; S4, concrete is poured to the 3D template of each unit plate; S5, a keel is installed at the installation position; and S6, the poured double-curved-surface UHPC curtain wall unit plates are positioned and installed at the corresponding positions of the keel correspondingly. According to the method, the appearance of a single curved surface of a traditional curtain wall is changed, the building elevation effect is enriched, the prefabrication machining and accurate positioning construction efficiency of the double-curved-surface UHPC curtain wall unit plates is improved, and the method has the advantages of environmental protection, construction cost reduction, construction progress acceleration and constructionquality improvement.

Description

technical field [0001] The invention relates to the field of construction methods for hyperboloid UHPC curtain wall unit plates. More specifically, the present invention relates to a construction method of a hyperboloid UHPC curtain wall unit plate based on BIM technology. Background technique [0002] At present, with the development of cities and the change of people's aesthetic concept of buildings, the image of buildings has become more and more important. In order to adapt to these changes, building curtain walls have been seeking changes and innovations, and have also developed rapidly in China. Special-shaped hyperboloids The emergence and development of the curtain wall has given the curtain wall a platform to give full play to its space, but the pouring and construction of the special-shaped hyperboloid curtain wall is difficult, and the later operation and maintenance replacement is more complicated. The existing technology is scarce, and the production and install...

[0002] At present, with the development of cities and the change of people's aesthetic concept of buildings, the image of buildings has become more and more important. In order to adapt to these changes, building curtain walls have been seeking changes and innovations, and have also developed rapidly in China. Special-shaped hyperboloids The emergence and development of the curtain wall has given the curtain wall a platform to give full play to its space, but the pouring and construction of the special-shaped hyperboloid curtain wall is difficult, and the later operation and maintenance replacement is more complicated. The existing technology is scarce, and the production and installation accuracy of the special-shaped hyperboloid curtain wall panels are difficult to guarantee. , resulting in slow development and application
